Internal thermal relay (contact capacity, AC 240V, 2A max, Normally ON
(b-contact), internal thermal fuse (unrecoverable)
* : Value in ( ) indicates the allowable braking ratio for 400V class.
Note 1:Thermal relay and fuse are built into the braking resistor.
Note 2: Internal thermal fuse prevents excessive heat generation which may occur
due to misoperation (unrecoverable).
Note 3: An appropriate safety circuit is configured so that the main power of the
robot driver is turned off if the thermal relay is tripped (an alarm occurs).
